问题     War atrocities are sometimes committed by " normal" people because they obeyed orders. Researchers from the Netherlands Institute for Neuroscience in Amsterdam measured brain activity while participants inflict pain, and found that obeying orders reduced empathy- and guilt-related brain activity for the inflicted pain. This may explain why people more readily commit immoral acts under coercion.
    The Nuremberg trials are full of cases in which humans commit atrocious crimes but show disturbingly little guilt—because they just "follow orders". Are they fundamentally different from us, or do we all have it in us to dull our conscience when we follow orders?
    Most people are averse to harming others. In a study published in PNAS in 2014, Molly Crockett gave people a chance to pay money to reduce shocks to themselves or to an anonymous other. Most actually paid more to reduce the pain of others than they paid to reduce their own pain. One of the reasons why the pain of others is so aversive to us is that our brain is empathic. If you measure brain activity while people observe the pain of someone else, you consistently find that the observer activates their insula and anterior cingulate cortex-regions normally activated when they feel pain on their own body—as if the observer were in pain themselves. The brain transforms the witnessed pain of someone else into the witness’ own pain. Together with moral ideals, this empathic brain activity is thought to be part of what keeps us from harming our fellow humans.
    So what happens when any of us follow orders? In an experiment we just published in the journal Neurolmage, we had people participate in pairs. Participant A went into the fMRI scanner to measure brain activity, while participant B went in front of a camera, with electrodes connected to their hand. Participant A could now decide whether to give, or not to give, little shocks to participant B, knowing that for each shock to B, A would get 5 cents. The shocks were unpleasant, but tolerable, and A could see B’s hand twitch each time they gave B a shock. The key manipulation was that in 60 trials, A was free to choose whether to give shocks or not, while in the other 60 trials, A heard the experimenter order them to give a shock on half the trials and not to give a shock on the other half.
    The results were quite striking. The vast majority of participants never disobeyed an order to deliver a shock, and gave the full 30 shocks they were ordered to give. In contrast, on trials in which they were free to choose, they only delivered 23 shocks on average, deciding not to give shocks on more trials than they decided to give shocks. When asked how guilty they felt about delivering shocks, they reported feeling less guilty when following orders than when freely deciding to deliver a shock. So orders increase the willingness to inflict pain, and reduce the feeling of guilt. Using fMRI, we looked specifically at how strongly A would activate their own pain system (including the insula and anterior cingulate cortex) while witnessing the shocks they inflict on B. This activity was clearly reduced when following orders.
    These results help us understand the terrifying mystery of war atrocities. We are all empathic beings who normally suffer when we harm other people. But if we obey the orders of others, this empathy is reduced. Our conscience is dulled, and the brakes on our violence are weakened.
The results of the author’s experiment is ________ Molly Crockett’s study.
选项 A、contrary to
B、consistent with
C、more successful than
D、a prelude to
答案B
解析 归纳对比题。根据题干提示定位到第五段。在第五段中，作者主要详述了自己做的电击实验的研究结果。根据实验结果，按命令行事的参与者完成了完完整整的30次电击，且疼痛系统的激活程度低；而自主选择电击与否的参与者实施的电击次数要少，且内疚程度更高。这一结果与莫利.克罗基特的结论是一致的，因此答案选[B]。[A][C][D]均不符合前后文的逻辑关系。
